SEWAGE TREATMENT PLANT Treatment plant for treating sewage in the project site has been proposed for a capacity of 500 m3/day. The Sewage Treatment flow chart is shown in below figure.

Sewage treatment plant based on Fluidized Aerobic Bio Reactor (FAB) technology The raw sewage will be collected in a collection sump and pumped to mechanical bar screen chamber for removal of large floating matter followed by grit removal in Grit Chamber. The raw sewage will then be collected in an equalization tank for homogenization of hydraulic load. The tank contents will be kept in suspension by means of course bubble serration through pipe grid. The equalization tank, with air flow indicator for continuous monitoring of air supply to the tank in order to avoid septic conditions, will be covered from top (RCC or FRP) to avoid nuisance. The equalized effluent will then be pumped to two Fluidized Aerobic Bio Reactors (FAB) in series where A - 3 BOD/COD reduction can be achieved by virtue of aerobic microbial activities. The oxygen required will be supplied through coarse air bubble diffusers. The bio-solids formed in the biological process will be separated in the down stream Tube Settler. The clear supernatant will gravitate to the chlorine contact tank where sodium hypochlorite will be dosed for disinfection of treated water prior to disposal.

Fluidized Aerobic Bio Reactor (FAB) Conventional effluent treatment plants are large sized, power intensive and require a lot of monitoring. Scarcity of open space and rising land a power costs have forced the industries to look out for space saving, compact and efficient treatment options. This has led to the development attached growth processes where the bio mass is retained within the aeration tank obviating the need for recycle. These plants are not only compact but also user friendly. The endeavor to have a continuously operating, no-clogging biofilm reactor with no need for back washing, low head-loss and high specific biofilm surface area culminated in the most advanced technology of aerobic biological fluidized bed treatment where the biofilm (biomass) grows on small carrier elements that move along with the water in the reactor. The movement is normally caused by aeration in the aerobic version of the reactor.

The reactor combines all the advantages and best features of Trickling filters, Rotating biological contractors, activated sludge process and submerged fixed film reactors while eliminating the drawbacks of these systems. The plants are more compact and more energy efficient.

The Fluidized Aerobic Bio Reactor (FAB) consists of a tank in any shape filled up with small carrier elements. The elements are made up of special grade PVC or polypropylene of controlled density (shown in plate). For media of specific gravity 0.92-0.96 the overall density could be expected to increase up to 9.5% when full of biomass such that they can fluidize using an aeration device. A biofilm develops on the elements, which move along the effluent in the reactor. The movement within the reactor is generated by providing aeration with the help of diffusers placed at the bottom of the reactor. Then thin biofilm on the elements enables the bacteria to act upon the biodegradable matter in the effluent and reduce the BOD/COD content in the presence of oxygen available from the air that is used for fluidization.

2.7. Give details of the water requirements met from water harvesting? Furnish details of the facilities created.

Rain water harvesting facilities like recharge pits, bio swales, rain gardens shall be developed apart from roof top rainwater harvesting. Roof top rain water shall be reused for landscaping.

F1A - 8 Rainwater Harvesting: The quantity of rainwater, which can be harvested, depends upon the annual rainfall, the area of the plot (catchment area) and soil characteristics. The amount of water infiltrated into soil varies with the condition of soil surface and the moisture content of the soil at the time of rainfall. The total amount of water infiltered depends on the infiltration opportunity time, which depends mainly on the slope of the land and the field structure like contour bunds, terraces and other structures, which tend to hold the runoff water over long periods on the land surface. Roof top water shall be used for domestic purpose/landscaping after filtration and disinfection.

2.8. What would be the impact of the land use changes occurring due to the proposed project on the runoff characteristics (quantitative as well as qualitative) of the area in the post construction phase on a long-term basis? Would it aggravate the problems of flooding or water logging in any way? The impact of project on physiography is a function of the rocky terrain of the area. The project area has a plain land and the design stage deliberations have ensured that the major contours are not disturbed.

F1A - 9 The project will have a positive impact on the soils and soil quality as project will have landscaping and the soils will be protected due to conservation. During the occupation stage, compaction will not occur, and the compaction if any will be restricted to road ROW. And the road ROW compaction cannot be said to be an impact of the operation stage as the pavement itself is a function of compacted base and sub base. Storm water drains and cross drainage structures will ensure no impact of increased run off. The project activity will be provided with a Sewage Treatment Plant to treat the domestic wastewater and necessary infrastructure will be provided for the safe disposal of domestic wastes to protect the water bodies.

2.9. What are the impacts of the proposal on the ground water? (Will there be tapping of ground water; give the details of ground water table, recharging capacity, and approvals obtained from competent authority, if any) There will not be any tapping of ground water.

2.10. What precautions/measures are taken to prevent the run-off from construction activities polluting land & aquifers? (Give details of quantities and the measures taken to avoid the adverse impacts) Construction activity will take up only during non-monsoon season. There are no major drains in the site. All material dumps shall be located away from the natural drains. Storm water drains shall be constructed before the construction of the building.

2.11. How is the storm water from within the site managed? (State the provisions made to avoid flooding of the area, details of the drainage facilities provided along with a site layout indication contour levels) Storm water drains: Storm water drains will be provided all over the proposed site to meet the expected increase in the runoff during rainy season due to the impervious nature of the roads and other paved areas. The site is uneven and it is proposed to maintain the levels as much as possible, hence storm water outlets from the site are anticipated. The expected runoff is calculated for the design of the storm water management plan is presented in following table

Rainwater pipes shall be designed for rainfall intensity of 40mm/hour from terrace floor to be harvested by storm water sumps adjacent to each building, excess disposed to external storm water lateral drain running adjacent to the periphery of the campus. The storm water drain has been proposed taking into consideration the site profile (contour).

F1A - 11 PROCESS DESCRIPTION: The raw sewage will be collected in a collection sump and pumped to mechanical bar screen chamber for removal of large floating matter followed by grit removal in Grit Chamber. The raw sewage will then be collected in an equalization tank for homogenization of hydraulic load. The tank contents will be kept in suspension by means of course bubble serration through pipe grid. The equalization tank, with air flow indicator for continuous monitoring of air supply to the tank in order to avoid septic conditions, will be covered from top (RCC or FRP) to avoid nuisance. The equalized effluent will then be pumped to two Fluidized Aerobic Bio Reactors (FAB) in series where BOD/COD reduction can be achieved by virtue of aerobic microbial activities. The oxygen required will be supplied through coarse air bubble diffusers. The bio-solids formed in the biological process will be separated in the down stream Tube Settler. The clear supernatant will gravitate to the chlorine contact tank where sodium hypochlorite will be dosed for disinfection of treated water prior to disposal.

The biological sludge generated in the FAB and settled in the tube settlers will be collected in a sludge sump and then pumped to sludge drying bed for de watering. The dried sludge will then be disposed off suitably as manure. The schematics of the process are shown. The two main components of the treatment system viz. The FAB reactor and tube settler are described in the following sections.

Fluidized Aerobic Bio Reactor (FAB) Conventional effluent treatment plants are large sized, power intensive and require a lot of monitoring. Scarcity of open space and rising land a power costs have forced the industries to look our for space saving, compact and efficient treatment options. This has led to the development attached growth processes where the bio mass is retained within the aeration tank obviating the need for recycle. These plants are not only compact but also user friendly. The endeavor to have a continuously operating, no- clogging biofilm reactor with no need for back washing, low head-loss and high specific biofilm surface area culminated in the most advanced technology of aerobic biological fluidized bed treatment where the biofilm (biomass) grows on small carrier elements that move along with the water in the reactor. The movement is normally caused by aeration in the aerobic version of the reactor.

The Fluidized Aerobic Bio Reactor (FAB) consists of a tank in any shape filled up with small carrier elements. The elements are made up of special grade PVC or polypropylene of controlled density (shown in plate). For media of specific gravity 0.92- 0.96 the overall density could be expected to increase up to 9.5% when full of biomass such that they can fluidize using an aeration device. A biofilm develops on the elements, which move along the effluent in the reactor. The movement within the reactor is generated by providing aeration with the help of diffusers placed at the bottom of the reactor. Then thin biofilm on the elements enables the bacteria to act

F1A - 12 upon the biodegradable matter in the effluent and reduce the BOD/COD content in the presence of oxygen available from the air that is used for fluidization.
